Ever tried Miso soup? We love it. Miso is a thick paste made from fermented soy beans. It’s salty. I like to describe it as being like a soup base. It’s been eaten in Japan and China for years. Now, it’s popular in the West for the health-conscious “because of its many anti-aging benefits. Miso and other fermented foods and drinks help build up the inner ecosystem and assure the digestive tract is amply supplied with beneficial bacteria. These bacteria help digest, synthesize, and assimilate nutrients so necessary for good health and anti-aging. They also strengthen the immune system, keeping it at the ready to fight infection and cancer.

Put a little broth into a pot and cook the vegetables until tender over med-high heat. Add the rest of the broth, the tofu cut into bite-sized pieces and the Shiratake Noodles. Cook until boiling. When it reaches a boil, add the Miso and dissolve. Simmer for 5-10 more minutes.
